Introduction
In today's world, building management systems are becoming increasingly popular. They allow building owners and managers to control and monitor various systems within their buildings, including HVAC systems. If you have a mini split device, you may be wondering how to connect it to your building's BMS or BAS. The answer lies in accessing the Bacnet menu on your device.
What is Bacnet?
Before we dive into how to access the Bacnet menu on your mini split device, let's first define what Bacnet is. Bacnet is a communications protocol used in building automation and control systems. It allows various systems within a building to communicate with each other, including HVAC systems, lighting systems, and security systems.
What is a Mini Split Device?
A mini split device is a type of HVAC system that is designed to cool or heat a single room or area. It consists of an indoor unit and an outdoor unit, which are connected by refrigerant lines. Mini split devices are becoming increasingly popular due to their energy efficiency and ease of installation.
How to Connect a Mini Split Device to a BMS or BAS
To connect your mini split device to your building's BMS or BAS, you'll need to access the Bacnet menu on your device. This will allow you to configure the device's settings so that it can communicate with the BMS or BAS.
Accessing the Bacnet Menu on a Mini Split Device
To access the Bacnet menu on your mini split device, you'll need a RS485 to USB adapter. Once you have the adapter, follow these steps:
1. Connect the adapter to your computer and to the mini split device.
2. Configure the dip switches on the device to enable communication with your computer.
3. Check your computer's drivers to ensure that it can communicate with the device.
4. Check the device in Device Manager to ensure that it is working properly.
5. Change the device instance or device ID to avoid conflicts with other devices on the network.
6. Cycle power after making changes to ensure that they take effect.
Setting Up the Node Addresses
Before you can access the Bacnet menu on your mini split device, you'll need to set up the node addresses. This involves configuring the dip switches on the device. Follow these steps:
1. Set switches 1-5 to "on" and switches 6-8 to "off".
2. Connect the wires from the device to the BMS or BAS.
3. Cycle power to the device to ensure that the changes take effect.
Configuring the Dip Switches
Once you have set up the node addresses, you'll need to configure the dip switches on the device to enable communication with your computer. Follow these steps:
1. Set switch 1 to "on" and all other switches to "off".
2. Connect the RS485 to USB adapter to your computer and to the device.
3. Check your computer's drivers to ensure that it can communicate with the device.
4. Check the device in Device Manager to ensure that it is working properly.
Checking Your Computer's Drivers
Before you can communicate with the device, you'll need to ensure that your computer has the necessary drivers installed. Follow these steps:
1. Connect the RS485 to USB adapter to your computer.
2. Check Device Manager to see if the device is listed.
3. If the device is not listed, install the necessary drivers.
Checking the Device in Device Manager
Once you have installed the necessary drivers, you can check the device in Device Manager to ensure that it is working properly. Follow these steps:
1. Connect the RS485 to USB adapter to your computer and to the device.
2. Check Device Manager to see if the device is listed.
3. If the device is listed, check its properties to ensure that it is working properly.
Changing the Device Instance or Device ID
To avoid conflicts with other devices on the network, you'll need to change the device instance or device ID. Follow these steps:
1. Access the Bacnet menu on the device.
2. Change the device instance or device ID to a unique value.
3. Save the changes and cycle power to the device.
Cycling Power After Making Changes
After making changes to the device's settings, you'll need to cycle power to the device to ensure that the changes take effect. Follow these steps:
1. Disconnect the device from the BMS or BAS.
2. Cycle power to the device.
3. Reconnect the device to the BMS or BAS.
